    Array

    #include <conio.h>
    #include <stdio.h>

    char phrase[50];
    int count;

    int cvowel();

    void main()
    {
    clrscr();
    printf("Enter a phrase :");
    gets(phrase);
    count = cvowel();
    printf("The number of vowels are : %i\n",count);
    printf("New Phrase :%s ",phrase);
    getch();
    }
    int cvowel()
    {
    int value=0;
    int index;

    for(index= 0;index<0;index++);
    {
    if (((phrase[index] == 'a') || (phrase[index] == 'e')) ||
    (phrase[index] == 'i') || (phrase[index] == 'o') ||
    (phrase[index] == 'u'))
    {
    value++;
    phrase[index]='X';
    }

    }

    return value;
    }

    I cant make this program run on one full phrase but i can run with a single character...

    Well, first of all, main is supposed to return an int. Fix that. Secondly, use fgets(), which is like gets(), only safer, as it prevents the user from entering morecharacters than your array can handle. Also, what is the getch() doing at the end of main()?

    in cvowel()
    erase the ; at the end of for
    for(index= 0;index<0;index++);<--------

    Then change it like this;

    for(index = 0; index < 50; index++)

    Actually this is a correction to what starX said

    There are three ways to write main with no arguments
    int main()
    {
    ...
    ...
    return 0;
    }

    main()
    {

    return 0;
    }

    void main()
    {


    }

    Also fgets is for reading strings from a FILE stream.
    Also I think that getch is for waiting for the user to end program
    by pressing some key

    Question

    What is the “;” doing after “for(index= 0;index<0;index++);” ?

    It will cancel the loop and only the 1st character will be checked and counted.

    ozgulker, fgets can read from stdin, and everything I've ever read tells me that main returns an int, it may work other ways, but I know it is supposed to return an int.

    I'm sorry about fgets, starX. Yes you are right about it.

    However for operating systems, main is just another regular function which returns or do not return anything. (it maybe int, char, long, float etc, nothing).

    Also the last return statement at the end of main returns that value to operating systems. It is possible for example in UNIX to write code that uses that return value, so it is not a dummy statement.
